Do any of you use groupon? They put one or a few deals up ever day - usually at 50% or better, and you have until the end of the day to buy into them or not.
While they are all kinds of things sold via groupon, I see a lot of spa deals, dining and drink deals and hotel savings in my local area.
It's something you have to look at every day - they will send you an email or you can go to their site at: http://www.groupon.com/ and generally the deals only are on sale for that one day.
They have a smartphone app, too - so you can check for deals on the go.
